LEVI JAMES MASTERSON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF TWO-THIRDS HIS RIGHT TO GEORGE H. GOLKET, OF SAME PLACE.

IMPROVEMENT IN MACHINES FOR TWISTING METAL.

Specification forming part of Letters Patent No. 156,583, dated November 3, 1874 application filed I September 26, 1874.

To all whom it may concern:

Be it known that I, LEVI JAMES MASTER- SON, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Twisting Metal; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. v

The nature of my invention consists in certain improvements'upon the machine for twistin g metal for which Letters Patent No. 152,501 were granted to me June 30, 1874, as will be hereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a plan view. Fig. 2 is a longitudinal section on line a: w of Fig. 1; and Figs. 3, 4., and 5 are details.

A represents the frame of my machine, conings at each end of the frame A are ordinary grooved rolls B B and B B for rolling the metal. 0 represents a frame, provided with hollow journals as a, which are arranged in bearings between the two sets of rolls B and B, and on a line with the grooves thereon. In the lower part of the frameG is pivoted a guide and twisting roll, D, and a correspond ing lifting-roll, D, is pivoted above it in a frame, 0, which is hinged in the upper part of the frame 0. In the hinged frame 0 is hinged an arm, b, from which projects a segmental rack-bar, Above the frame 0 are two shafts, E and E, which are parallel with each other, and with the rolls B B. The shaft E is' revolved by suitable gearing from either set of feed-rolls, and on the same is fastened a bevel-pinion, f, which gears with a double pinion, h, placed on a stud, e, projecting from a clamp, G, fastened on the stationary shaft E.

The pile or billet of iron or other metal, having first been sufficiently heated for.rolling, is passed through between the rolls B B,

and enters the hollow journal (1. The metal is carried by. the action of the rolls 8 B into the frame 0 between the rolls D D. These latter rolls may be constructed substantially as-shownthat is, the lower roll D have a deep circumferential groove, into which the metal enters, and the upper lifting-roll D fit in saidgroove-or in any other suitable manner. As the metal enters between these rolls the upper roll D, with the frame 0, arm I), and rack-bar d, is raised by the metal sufficiently to throw the segmental rack 01 in gear metal is the same as fully described in my former patent, above referred to.

By having the segmental rack of suitable size, a quarter-turn, half-turn, or any other degree of turn, may be given to the frame.

When a slow motion of the frame is required, the pinion fand clamp G, with its pinion, are loosened from their places upon the respective shafts, and a worm, I, moved up into place, and fastened on the shaft E, so that the segmental rack-bar, when thrown upward by the metal, will gear therewith.

This invention is applicable to existing rolls, and any number may be used in a train of rolls, as may be desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The frame O, provided with hollow jour nals a a, combined, substantially as herein described, with the stationary revolving guide and twisting roll D, and the movable revolving lifting-roll D, as and for the purpose herein set forth.

2. The hinged frame 0, in combination with the guide and twisting r011 D, the hinged In testimony that I claim the foregoing as arm b, and segmental rack d, substantially as my own I affix my signature in presence of and for the purpose specified. two Witnesses.

3. The combination of the roll D, frame 0, LEVI J. MASTERSON. hinged in the frame 0, the arm b, and rack d, Witnesses: with pinions h f and revolving shaft E, for O. H.WATSON,

the purposes set forth. H. A. HALL.
